Effect of High Strength Clad Foil on Cycle Life of SiO Anode

摘要

Electric vehicles with longer driving range requires higher energy density materials such as Silicon and Silicon monoxide (SiO) as anode material. They are known of volume expansion and shrinkage during cycles which leads deformation of Cu foil and deteriorates cycle life of lithium ion batteries. Increasing foil thickness is not desirable from energy density point of view. In such a case, anode foil needs strength to suppress deformation, as well as low resistance.
